Ethnobotanical study on medicinal plants from the Dragon Boat Festival herbal markets of Qianxinan, southwestern Guizhou, China

Dragon Boat Festival herbal markets in the Qianxinan Buyi and Miao Autonomous Prefecture of southwestern Guizhou have a long well-conserved history.These markets,which are a feature of Buyi and Miao traditional medicines,contain a rich diversity of medicinal plants and traditional medical knowledge.Today,people in southwestern Guizhou still believe that using herbs during the Dragon Boat Festival prevents and can treat disease.In this study,we identified the fresh herbal plants sold at the herbal markets of Xingren City and Zhenfeng County in Qianxinan Buyi and Miao Autonomous Prefecture and quantified their importance.We identified 141 plant species(belonging to 114 genera and 61 families).The plant family with the most species was Asteraceae(14 species).Informants reported that most medicinal plants are herbaceous,with 95.7%of plants used for decoction and 30.5%used for medicinal baths.Medicinal plants are most commonly used to treat rheumatism,injury,and abdominal diseases.The utilization frequency index and relative importance values indicated that Artemisia argyi and Acorus calamus are the most important plants sold at herbal markets during the Dragon Boat Festival.The price of medicinal materials sold in the market may serve as an indicator of the conservation status of species in the region.These findings indicate that the Dragon Boat Festival herbal markets in the Qianxinan Buyi and Miao Autonomous Prefecture fully embodies the characteristics of indigenous ethnomedicine and culture,and also exhibits the diversity of plant resources.We recommend that rare and endangered plants in this region be domesticated and protected.

THE STRONG DRAGON BOAT RACE PRECIPITATION OF GUANGDONG IN 2008 AND QUASI-10-DAY OSCILLATION

Guangdong suffered from the most serious precipitation of its corresponding time during the dragon-boat race of 2008 since 1951.The relationship between the strong dragon-boat precipitation in 2008 and atmospheric low-frequency oscillation was analyzed with the methods of wavelet analysis,correlation and Lanczos filter.Results showed that the daily rainfall exhibits a significant 7 to 12-day quasi-periodic oscillation(namely quasi-10-day oscillation) during the precipitation,the daily 500 hPa height over Guangdong exhibits a significant 8 to 13-day quasi-periodic oscillation,and the daily 850 hPa zonal wind averaged over the north of the South China Sea presents a significant quasi-12-day periodic oscillation.The Guangdong rainfall during the annually first rainy season is most closely correlated with monsoon over the north of South China Sea,and less closely with an upper-level trough at 500 hPa affecting Guangdong.Strong monsoon surges induced two heavy rainfall processes in 2008.The monsoon surges joined with a westward-propagating quasi-10-day oscillation that originated from the central Pacific and was enhanced in a strong convective region east of the Philippines and a northward-propagating monsoon that originated from the southern South China Sea was enhanced.With composite analysis of typical phases,the common evolution characteristics of atmospheric circulation of the two heavy rainfall processes were analyzed for different phases.These features can be used as reference for medium prediction of heavy rainfall processes in Guangdong.

The Dragon Boat Festival: Combining Boat Racing with Tradition

THE Dragon Boat Festival is a traditional Chinese festival which originated from the worship of celestial phenomena, and evolved from Dragon totem sacrifice in the remote ages. The festival falls on the fifth day of the fifth lunar month (June 7 on the solar calendar 2019). To celebrate the Dragon Boat Festival, people pray for blessings and protection against calamities with vibrant and colorful festivities. The Dragon Boat Festival began to be observed around the Spring and Autumn Period and the Warring States Period more than 2,000 years ago.

A Study on the Transformation of the Chinese Dragon Boat Festival in Japan

The Japanese Dragon Boat Festival originates from China. It was first carried to Japan in the 7 th century, gradually developed into Men's Day after more than one thousand years of transformation from routine royal activities and female sacrificial activities, and finally converted into Children's Day today. The Japanese reform of the Chinese Dragon Boat Festival range from the types of celebrations to its meaning with regard to native customs and habits. Although the Japanese government modified and complemented the festival in various historical stages, forming a Dragon Boat Festival with Japanese characteristics, the Japanese Dragon Boat Festival is still heavily loaded with Chinese cultural elements.

2022年华南极端“龙舟水”与大气环流及海温异常的关系

利用华南192个国家气象观测站逐日降水资料,NCEP/NCAR大气环流再分析资料,NOAA月平均海表温度资料(ERSST V5)及向外长波辐射(OLR)资料,采用相关、合成分析的方法研究了2022年华南“龙舟水”异常与大气环流及海温异常的关系。结果表明,2022年“龙舟水”期间,东亚大槽、东北冷涡偏强,南下冷空气偏强,同时西太平洋副热带高压和南支槽均偏强,在华南存在明显的水汽辐合。2022年发生的拉尼娜事件,大气环流对其有明显响应,Walker环流增强,华南对流明显加强,菲律宾以东存在异常反气旋环流,副高加强导致其西北侧的西南风加强,向华南水汽输送显著增强,同时华南存在显著的上升运动。大气环流和海温的异常导致2022年华南极端“龙舟水”。

近62 a华南“龙舟水”气候特征及变化

每年端午节前后龙舟竞渡之时,是华南前汛期降水最多、最为集中的时段,容易引发严重洪涝灾害,并对早稻生产造成严重影响,称之为“龙舟水”。对华南“龙舟水”期间暴雨过程的频次和强度进行研究是当前防灾减灾的迫切需求。利用1961—2022年华南192个国家气象观测站逐日降水资料,采用EOF、线性趋势、M-K突变等方法,分析了华南“龙舟水”期间降水量的时空特征及变化;构建了一个表征华南“龙舟水”暴雨过程的综合强度指数,由此分析华南近62 a“龙舟水”期间暴雨过程频次、强度以及“龙舟水”强度年景指数的特征和变化。结果表明,华南“龙舟水”一致性变化是其最主要的特点。1961—2022年“龙舟水”期间,华南共出现229次暴雨过程,平均每年3.7次。近62 a来华南区域平均“龙舟水”降水量和暴雨过程频次变化趋势不显著,但“龙舟水”强度年景指数以1.2·(10 a)^(-1)的速率显著上升。评估得到近62 a华南“龙舟水”最强暴雨过程出现在2022年6月4—21日,华南“龙舟水”强年有4 a,分别出现在2022年、2020年、2008年和2006年。

基于改进YOLOv8n-seg的蟹塘水草区域分割与定位方法

目前蟹塘内水草清理以人工作业为主,劳动强度大,作业效率低,自动水草清理船能大幅降低劳动强度,提高作业效率,而确定蟹塘水草分布是规划水草清理船高效作业路径的关键基础。针对无人机采集的蟹塘水草图像中水草与岸边植被相似性高、难以准确区分等问题,该研究提出一种基于改进YOLOv8n-seg的蟹塘水草区域分割与定位方法。改进模型从降低模型大小和提高召回率的角度出发,首先基于RT-DETR(real-timedetectiontransformer)的HGNetv2(hierarchical graph network)轻量化网络结构重设主干特征提取网络,缩减模型体积;其次以Efficient Rep轻量化结构为基准重构颈部网络,在降低参数量的同时增强模型的多尺度特征融合能力;接着在特征提取层引入SegNext注意力机制,加强模型对蟹塘水草区域的敏感度。为了消除模型在识别过程中产生的冗余区域,进一步提高分割精度,采用二值化处理对分割结果进行优化,并结合图像处理算法对水草区域进行面积筛选;经过坐标转换后得到精确水草轮廓经纬度坐标。试验结果表明:改进模型对蟹塘水草具有良好的区分度和分割效果,其参数量和计算量分别为1.49 M和8.4 GFLOPs,召回率和平均精度均值分别为91.5%和95.6%,与原YOLOv8n-seg模型相比,模型体积减小了49.7%,分割速度提升了32.3%。在坐标转换试验中,水草定位精度平均误差为0.22 m,验证了改进模型能够满足蟹塘水草区域分割与定位要求。研究结果为后续水草清理船自动作业路径规划研究提供参考。

泰和县钟埠村"拖龙船"仪式音声的建构及象征

仪式音声是近二十年来出现的一个重要学术概念,它从仪式整体的语境中分析音声对于仪式作为一种人类学意义上的“文化表演”过程的重要意义。文章以泰和“拖龙船”仪式为研究对象,结合传统的发明、象征人类学的理论与方法,从“音声”切入,置“音声”于仪式或信仰的共生环境中探寻其内涵和意义。对于“拖龙船”仪式而言,执仪人“文化表演”所形成的“音声声谱”有着从“象”到“意”的隐喻,形成一个“符号(基本单位)-仪式(聚集体)-象征(意义)”的动力循环圈。音声在保持仪式进行有效性的同时,不但赋予娱人娱己双重功能,还在不同的仪轨环节中,具有不同的象征意义。
